I'll join the minimalists here. For the past decade, I've only had about 6 shirts, two pair of denim pants, one pair of boots, 4 pairs of socks, a rain coat and a jacket. I go through one pants every 2 years (as it gets riddled with holes I can't patch up anymore). Most but a few are black and made out of wool. Having worn wool clothing, it's hard to go back to cotton, linen or synthetic. Not only wool dries super fast and regulates body temperature better, it doesn't get smelly as fast as the other fabrics. Black color hides hard to remove stains that otherwise would require harsh chemicals to get rid of, reducing the fabric's life.

The main reason for living this way is not to have to spend brain cycles deciding what to wear every day.
